Thanks a lot :)
I’ll investigate that bug and try to get it fixed ASAP.
I think you’re on to something with having traffic lights default to red, it does make more sense that way. I’ll test it and add it if it’s doesnt have any unintended consequences.
Slowing the sim makes sense I’ll try to add it soon. (You can already speed up the sim by pressing 1,2 and 3 if you didn’t already know)
Making it easier for players to debug car paths is high on my priority list but it’s quite a hard problem to solve. I’m working on quite a few things which will hopefully improve things.
